Lemon Asparagus Pasta
This Lemon Asparagus Pasta is a bright, springtime dish that comes together in under 30 minutes. Tender-crisp asparagus and al dente spaghetti are tossed in a light, silky lemon-butter sauce with freshly grated Parmigiano Reggiano and a generous hit of lemon zest. It's weeknight-friendly, vegetarian as written, and endlessly flexible — serve it as a meatless main or bulk it up with grilled shrimp or chicken without changing a thing about the base recipe.

- Ladle or measuring cup For reserving pasta water
- Large serving bowl or pasta bowls For serving
Ingredients
- 12 oz spaghetti or linguine pasta 340g
- 1 lb fresh asparagus 450g; tough ends trimmed, cut into 2-inch pieces
- 3 tbsp unsalted butter divided
- 4 garlic cloves minced
- 1/2 tsp red pepper flakes optional
- 2 large lemons zested; zest only the yellow outer layer, avoid white pith
- 2 large lemons juiced; about 1/4 cup (60ml) fresh lemon juice
- 1/2 cup reserved pasta cooking water 120ml; plus more as needed
- 2/3 cup freshly grated Parmigiano Reggiano about 60g; plus more for serving
- 2 tbsp extra virgin olive oil divided
- 1/4 cup fresh parsley roughly chopped
- salt and freshly ground black pepper to taste
Instructions
- Trim asparagus by bending each spear until it snaps, then cut into 2-inch diagonal pieces. Mince garlic, zest and juice both lemons (you need about 1/4 cup juice), finely grate the parmesan, and roughly chop the parsley.
- Bring a large pot of generously salted water to a boil, add pasta, and cook until al dente per package directions (typically 8–10 minutes). Before draining, reserve at least 1/2 cup of pasta water, then drain — do not rinse.
- Heat 1 tbsp olive oil and 1 tbsp butter in a 12-inch skillet over medium-high heat. Add asparagus in a single layer, season with salt and pepper, and cook 2–3 minutes, tossing once, until bright green and tender-crisp. Transfer to a plate and set aside.
- Reduce heat to medium; add remaining 1 tbsp olive oil and 2 tbsp butter to the same skillet. Cook garlic (and red pepper flakes if using) for about 1 minute until fragrant, then add lemon juice, lemon zest, and 1/4 cup reserved pasta water; simmer 30 seconds, scraping up any browned bits.
- Reduce heat to low, add drained pasta and toss to coat. Add parmesan in two or three additions, tossing vigorously between each; add more pasta water a splash at a time if needed to create a silky, glossy sauce.
- Fold the sautéed asparagus and parsley into the pasta, taste and adjust seasoning with salt, pepper, or a squeeze of lemon. Serve immediately topped with extra parmesan, black pepper, and a drizzle of olive oil.
Notes
- Always use fresh lemon juice and zest — bottled juice lacks the brightness and complexity that makes this dish shine.
- Don't skip the pasta water. The starchy liquid emulsifies the butter and cheese into a smooth, glossy sauce. Reserve more than you think you'll need.
- Grate your own Parmigiano Reggiano. Pre-shredded cheese contains anti-caking agents that prevent it from melting smoothly into the sauce.
- Add parmesan off the heat or over very low heat in small batches, tossing continuously to prevent clumping.
- Cook asparagus separately in a hot skillet to keep it tender-crisp and vibrant green — adding it raw to the sauce results in a mushy texture.
- Salt your pasta water generously (it should taste like mild seawater) — this is your only opportunity to season the pasta itself from the inside.
- To add protein, sauté 1 lb peeled shrimp or sliced chicken in the skillet before the asparagus, cook through, set aside, and return with the asparagus at the end.
- For a creamy variation, stir in 1/4 cup heavy cream or cream cheese along with the lemon juice.
- Leftovers keep refrigerated in an airtight container for up to 3 days. Reheat in a skillet over medium-low with a splash of water, then finish with a squeeze of fresh lemon and extra parmesan.
- This dish does not freeze well — the butter-based sauce separates and the asparagus becomes mushy when thawed.
